Question

Solve for x:
2x + y = -2
4x + y = -8

Answer 1

Explanation:

x= −1 −y/2

​

x= 4 −8−y/4

​

Answer 2

x = -3

Explanation:

2x + y = -2

4x + y = -8

2x + y = - 2

y = -2x - 2

4x + y = - 8

y = -4x - 8

y = -2x - 2

y = -4x - 8

-2x - 2 = -4x - 8

4x - 2x = 2 - 8

2x = -6

2x/2 = -6/2

x = -3

To check just use da graph ;w;

The x is -3
